(d) and this vantage point, which combined with her talent for writing to make

(e) and this vantage point, combined with her talent for writing, made

Ans：E

mine: B(我也承认E没有错，但是B错在哪里呢？)

LZ的题目有难度啊！

我也只能抛砖引玉了：

29.因为主语已经是more than 10 times as much energy了，就不好用it 去指代了把？（不好意思我也选错了）

47.不需要be动词，因为这句话的主干不是在比较，这个as varied as 只是一个修饰成分。只有在A is（be动词) as + adj +as B (is)的时候才可能会需要be动词，可以说是为了两个比较对象的对称。而这里并不是这种情况。

62.B这里把vantage point作为一个同位语，指代前面句子的所有内容，可以说是把句子前面的内容当成subordinate了（成为次级内容），但是后面它又没有主级内容（即没有完整的句子），而是用了一个定语从句。所以感觉逻辑意思不清，比较奇怪...(不好意思，我语法不好，没法从语法的角度找到B的硬伤)

希望NN快点探出头抛玉。。。

47题楼上的解释很好，明白了。

62题在prep里面是这样解释的：

B: when combined状语从句应该在that以内，否则没有修饰对象

没懂是什么意思

when 是引导状语从句的, 似乎不能直接修饰名词point.

that 可以引导定语从句, 所以B答案that要放在point后面,when的前面,made 是point的谓语,前面不应放that.

我想他的意思应该是 when combined...是一个状语从句，必须修饰主句主语，而就像我前面所说的，这个后面不是一个完整的句子。所以没有修饰对象。如果放在that之后，他才可以修饰vantage point. " a vantage point that, when combined with..., made her one of the ...

但是即使是这样，后半部分是对了，但是整个句子结构还是不行。就变成了because ..., MOW was..., a vantage point. 如果vantage point是作为一个同位语，他应该是作为前面句子中的最后一个名词成分的同位语。而显然句意是想让他指代前面所有内容。

不知清楚没有。。。

LZ的题目问得好；

62题我是这么理解：

题目想表达的是两样东西vintage point 和writing talent, made her valuable, 而那个带when的选项，改变了这层逻辑意思。

29题不会，你确定答案是C?

我突然想到，是不是因为29的谓语实际上是is generated....所以必须要用was generated 来对应？？

29答案是C

是做prep时候给的答案

我选的时候觉得and后面it代表energy，was后面省略了generate through wind power

energy is generated through wind power now than it was (generated through wind power ) in 1990

29题

is generated是 后一部分的动词，如果要加上的话应该把 GENERATED 补上   不能只省略一半 使得was 便成谓语有歧义

29 题这里的was不能和前面的is平行对称，因为is在这里不是谓语动词，只是被动语态的一部分。所以补出was并不管用。我的理解。
